Patent ES-453591-A1 (ES)
Title: Integrated circuit isolation structure and method for producing the isolation structure
IPC: H01L21/76
Filed: 1976-11-24
Abstract: A semiconductor device, such as a transistor, integrated circuit or the like, having a pattern of oxidized and densified porous silicon regions extending onto one of its major surfaces for isolating regions of the semiconductor is manufacturable by a relatively simple process. The process involves forming porous silicon regions in the surface of the semiconductor body such as a silicon wafer, in the areas where dielectric isolation between semiconductor devices is desired. The porous silicon regions are then oxidized at a temperature sufficient to completely oxidize the porous silicon. The oxidiation is such that the oxidized porous silicon extends above the surface of the semiconductor wafer. The oxidized porous silicon regions are then subjected to a temperature higher than the oxidizing temperature utilized in the previous step to cause the densification of the oxidized porous silicon regions. The result of this densification step is the collapse of the porous oxide to a dense structure which is substantially planar with the surface of the semiconductor wafer. This densified silicon dioxide structure has an etch rate which is substantially the same as thermally grown silicon dioxide.

Title: Trailer towing devices.
IPC: B60D1/34
Filed: 1978-08-31
Abstract: Improvement of equipment for attaching trailers with inertia controlled braking arrangement, being of the type including stabilizing bars whose exposure to tension provides an coupling arrangement for nullifying the reaction force affecting the supports of the movable control components.

Characteristic is that this adverse force is generated by two elastically deformable arms freely articulated on a common axle located at the end of the coupling seat of the trailer. The free ends of either of these arms, usually curved downwards, is in permanent elastic abutment with the corresponding attachment bar. Elements are provided for keeping the arms on the bars during traction, turning and braking.
